call cancel() method didn't finish the operation!

[ichagall]

for the executing operations , call cancel() don't finish the operation really, the method just mark the operations' state as hasFinished and remove the operations from the queue, in fact these operations are still running.

@ichagall That is the expected behavior. cancel() just sets the state, but does not itself call finish() -- you have to also do that.

EDIT: Looks like PSOperations works differently from the WWDC Operations project. From what I can tell cancel() does in fact call finish() -- I think this makes more sense.

override open func cancel() {
        stateLock.withCriticalScope {
            if isFinished {
                return
            }
            
            _cancelled = true
            
            if state > .ready {
                finish()
            }
        }
    }
